LiF crystals were subjected to neutron irradiations between 7 x 10/sup 13/ and 3 x 10/sup 17/ nvt. The F-type center, exhibiting 29 or more ESPR hyperfine components whose separation and resolution depend on orientation of the applied magnetic field, was observed in all samples. The F-type center apparently does not arise from an impurity. Crystals subjected to x radiation yield the same spectrum. Crystals receiving small neutron dosages (~10/sup 14/ nvt) exhibit additional lines which are also obstable at room temperature, were found in crystals which have received neutron dosages of more than 10/sup 15/ nvt. Crystals which have received neutron dosages of 10/sup 18/ to 10/sup 19/ nvt exhibit an additional narrow, intense resonance apparently arising from conduction electrons in lithium metal formed by the irradiation. Progress is reported on studies of irradiated NaF. LiI, NaCl, KCl, KBr, KI, RhI, boron- containing glasses, azides, corundum, spinel, and rutile. (auth)
